In the UK today, there are an estimated 7.5 million CCTV cameras, roughly one camera for every eleven people, covering streets, shops, and homes. With smart home systems growing at over 20 % CAGR, many homeowners now install their own CCTV cameras for added security.
Knowing how to tell if a CCTV camera is on helps you protect your privacy, test your own system, and spot unauthorised surveillance. In this guide, we'll explain why it pays to check camera status, show the common signs that a CCTV camera is active, and share tips for detecting hidden units.
By the end, you’ll be fully prepared about how do you know if a CCTV camera is on around you and is recording.
Part 1: Why Check If a CCTV Camera Is On?
Ensuring that your CCTV cameras are actually active matters for privacy and legal reasons. If your camera unintentionally captures public areas or neighbours’ property, you must comply with the Information Commissioner’s Office (ICO) guidance.
Before you learn how to know if a CCTV camera is on, let's mention some further key reasons why it's necessary:
1. Legal Compliance
Recording people without clear notice can breach the Data Protection Act and UK GDPR. Ensuring your camera is active lets you display accurate "CCTV in operation" signs and fulfils ICO requirements.
2. Privacy Assurance
An unexpected live feed might capture neighbours, passers-by, or private areas. By confirming status, you control when and where recording happens, protecting everyone’s privacy.
3. System Dependability
Surveillance units may go offline if they lose main power, drop their network link, or develop hardware issues, often without any obvious sign.
By running quick status checks on your CCTV cameras (for example, the SoloCam S340 Wireless Outdoor Security Camera), you’ll spot faults early and keep them ready to record.
4. Crime Deterrence Power
An operating camera is a strong visual warning that discourages thieves and vandals. Verifying that your system is active ensures it continues to serve as an effective deterrent.
5. Admissible Footage
If an incident occurs, only recordings from a functioning camera can be used as proof. Regularly checking your setup prevents recording gaps and guarantees continuous coverage when you need it most.
6. Insurance Requirements
Many home insurance policies require proof of working surveillance to reduce premiums. Regular checks keep your coverage valid because an inactive camera could invalidate a claim.
Part 2: Common Signs a CCTV Camera Is On
Knowing how to tell if a CCTV camera is on often comes down to the quick checklist as enlisted below:
1. Power/Status LEDs
Many cameras feature small status lights, often red or green, near the lens or on the housing. A steady or blinking LED usually means the unit is powered and recording.
2. Infrared (IR) Glow
In low-light conditions, night-vision models emit a faint red glow from their IR LEDs. Block ambient light over the camera (for example, with a book); if you still see a red glow, it’s active.
3. PTZ Movement and Sound
Pan–tilt–zoom (PTZ) cameras often sweep or reposition themselves when running. Look for subtle rotations or hear a soft buzz from the motors during patrol or tour modes.
4. Live Feed in the App or Software
If you have access to the camera’s system interface, such as the web portal or mobile app, you can confirm operation instantly by viewing the live stream. A working feed means the camera is on and transmitting.
5. Lens Reflection
Point a torch or smartphone light at the lens at an angle. A recording lens often reflects a small, bright spot back to you, whereas dummy cameras use plain glass without the same reflective coating.
6. Low-Level Humming or Electronics Noise
Some cameras emit a barely audible hum from internal circuits or hard drives. Holding your ear close, without touching the device, can reveal this telltale sound.
7. Network or Router Check
Log in to your router’s admin page and inspect the list of connected devices. An unfamiliar IP or MAC address tied to a camera manufacturer indicates an active wireless camera on your network.
Part 3: Tips to Detect Hidden or Non-Functional Cameras
Want to uncover secret CCTV cameras or verify that your own devices are up and running? Try these expert troubleshooting methods to locate both hidden and inactive units:
1. Spotting Hidden Cameras
- Reflective Surfaces Test: Hold a small mirror or the screen of your smartphone at eye level and slowly scan suspect areas. A genuine camera lens will catch and reflect light, whereas mimic lights or dummy cameras won’t produce the same pinpoint flicker.
- RF Signal Scanner: Carry a portable RF scanner close to walls, upholstery and fixtures. When you get near an active camera’s transmitter, often operating on 2.4 GHz or 5 GHz, you’ll see a jump in signal strength.
- Night-Vision Light Check: In a dim room, point your phone's camera (night mode off) at areas like tinted windows or decorative objects. Genuine IR LEDs for night vision will show up as faint purple or white dots that you can't see with the naked eye.
- Heat-Signature Scan: Use a simple thermal camera to inspect ceilings and behind walls. Running electronics, such as a hidden CCTV camera’s processor or IR array, create small warm spots you can detect as bright patches on the thermal display.
2. Verifying Non-Functional Cameras
- App/Software Health Check: Log in to the manufacturer’s app or NVR (Network Video Recorder) dashboard and review your camera’s status. Any “offline,” “disconnected” or “signal lost” warnings mean the unit is inactive. Devices like the eufyCam S3 Pro will also display the remaining battery percentage and last-seen timestamp.
- Scheduled Recordings Review: Check your camera's recording schedule or motion detection logs. If no new clips have been saved in the past 24-48 hours, the camera may be powered on but not recording. This can be possibly due to a misconfigured sensitivity setting, storage full error or firmware fault.
- Night-Vision Function Test: After dusk, stand within the camera's field of view and use a torch briefly (then turn it off). If the live view remains clear in low light, night vision is active. Whereas a blank or dark feed suggests a non-functional IR system.
- Firmware and Network Audit: Ensure your camera’s firmware is up to date because outdated software can disable recording features or break connectivity. Also, review your router’s DHCP lease table for changes in IP assignment that might leave the device unreachable in your security app.
Conclusion
Being able to know how to tell if a CCTV camera is on is essential for protecting your privacy, following the law, and making sure your security setup does its job. Quick tests, such as checking status LEDs or hunting for IR illumination, show you which cameras are live.
For camouflaged camera units, you can go for reflective-surface tests and RF scanning to expose them. Finally, keep an eye on your cameras’ app statuses and recording logs to ensure they capture every moment.

Frequently Asked Questions
1. Can a CCTV camera be on without the red light?
Yes. Many modern cameras use "invisible" IR LEDs (940 nm) that emit no visible glow, so you won't see the usual red ring in darkness. Additionally, some models disable their status LEDs when idle or on low-power standby, only flicking them on when motion is detected or recording begins.
2. How to tell if a security camera is watching you?
To tell if a security camera is watching you, you can shine a torch at suspect devices. An active camera lens will reflect a pinpoint of light back to you. Besides, you can look for small, often green or red, status lights around the housing. A steady or blinking LED typically means it’s powered and recording.
3. How do I know if my security camera is active?
To confirm the activity of your camera, you can open the camera's mobile app or web portal. A working live stream confirms the unit is on and transmitting. Moreover, you can also look for LED indicators or slight pan/tilt motions in "patrol" modes of the supported cameras like eufy Indoor Cam S350.
